In the depths of the ocean, where sunlight light can’t get thru, life rages and you can join in the underwater bustle, in a form of a toothy fish with a flashlight between the eyes.
Life under the water is not so easy, especially if you are a small and defenseless fish, so try to gain weight as soon as possible, eating everything that is smaller, soon a flock of devoted fish will form around you and it will grow.
Beware of large jellyfish, they are poisonous, for the time being do not catch the eye of larger competitors with huge flocks, if they attack, your character will end up only as a miserable skeleton.
Crabs are neutral creatures, if they like to, they join your community.
Try to survive and become invincible.
